Reaction Steps

A mixture of 3-(5-fluoropyrid-2-yl)-5-(3-cyano-5-nitrophenyl)-1,2,4-oxadiazole (30 mg, 0.11 mmol), potassium carbonate (29 mg, 0.21 mmol) and ethyl iodide (98 μL, 1.2 mmol) in N,N-dimethylformamide (1 mL) was heated in a sealed vial at 140° C. for 2 hours. The reaction was cooled, diluted with ethyl acetate, washed with water (3×) and saturated brine, filtered and concentrated. Silica gel chromatography using hexanes:ethyl acetate:dichloromethane 3:1:4 afforded 3 mg (20%) of 3-(5-fluoropyrid-2-yl)-5-(3-cyano-5-diethylaminophenyl)-1,2,4-oxadiazole:
